Association control apparatus, association control method and service association system

ABSTRACT

In the service association system according to the present invention, an “association template” in which service association details are described is prepared in advance; an actual service adaptable to a template instructed by a user is extracted; a specific association operation description is generated by adapting the actual service instructed by the user to the template; and the service is operated in association. As the result, it becomes possible to construct a service association system in which different services can be automatically adapted to the template in addition to the service which simply adapted to the template.

TECHNICAL FIELD

The present invention relates to a system for operating services in association with each other, the service being received through home appliances and various servers connected to a network.

BACKGROUND ART

In recent years, a system for providing various services by operating, in association with each other, a server and personal computer connected to a network such as the Internet, domestic home appliances and the like has been proposed.

Herein, it is necessary to customize (i.e. determination of details of the associated operation and definition thereof) the associated operation of the home appliances and server that are connected to the network. This requires a user efforts for grasping about all details of the associated operation and efforts for specifying the operation so that it becomes a large work loads for the user. On the other hand, a method for a user to select an associated operation from all pre-prepared associated operations is suggested. However, this method is not realistic since the number of combinations is enormous. Therefore, a method of automatically generating an association path in the associated operation according to an instruction of a user is proposed (e.g. refer to Japanese Laid-Open Patent publication No. 2002-149405).

However, in the conventional method, the system automatically generates the association path so that a range of generable associated operations is limited to a self generation capability of the system (i.e. a range of pre-prepared associated operations in the system). As the result, there is a case where it cannot satisfy user's needs.

Accordingly, concerning the conventional problem, the present invention aims to provide a service association system and the like which can provide associated operations in response to the user's needs.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereafter, it is explained about embodiments according to the present invention with reference to the drawings.

FIRST EMBODIMENT

FIG. 1 is a configuration diagram of a service association system 2000 in a present embodiment. As shown in FIG. 1, in the service association system 2000, a home network 1000 is connected to a weather information supply server 10, a weather information supply server 20, and a news supply server 30, and the system operates appliances 160 to 190 in the home network 1000 by associating with information obtained by each server. Note that server functions of the weather information supply server and the news supply server are examples of the information supply unit.

Here, a “service” in the present invention refers receiving a supply of information and the like from appliances connected to the network and providing information and the like to the appliances. Also, a “network connection” refers connecting to a local area network (LAN) and to the Internet. In this case, the connection form can be either by wire or by wireless. Further, an “appliance” in the present invention, for example, includes: a home appliance such as air conditioner and washer; an audiovisual appliance such as television, speaker and camera; an electric appliance which can input and output information such as electric bulb, switch, vibrator and various sensors; a compact appliance which can input and output information such as stuffed-toy shaped robot, function attached umbrella, and hanger with a liquid crystal display; an information communication appliance such as telephone and fax; an information processing appliance such as personal computer and home server; a portable appliance such as cellular phone and GPS terminal; a public appliance such as automatic door and traffic light; an information supply server such as weather information supply server, a traffic information supply server and ranking information supply server; a private server which deals with information relating to an individual and a group such as mailing server, scheduler server, television program recording server and family-keeping server; and function supply server which supplies functions such as dictionary server, language translation server, sound recognition server, image recognition server, format conversion server and authentication server. Further, “service association” in the present invention refers to provide a service by associating with the plurality of appliances by combining obtaining information from the appliances and the like, processing the obtained information and to providing the processed information to appliances and the like.

As shown in FIG. 1, the home network 1000 includes an association control apparatus 100 and appliances 160 to 190. Further, the association control apparatus 100 is, for example, a personal computer for controlling the home network 1000 as a whole. It includes a communication control unit 110, an input/output unit 120, an association generation unit 130, and an association execution unit 140.

The communication control unit 110 is, for example, a micro computer having a ROM which holds control programs, RAM and the like. While it controls the association control apparatus 100 as a whole, it controls communication with other servers through network 50 and a communication with other appliances 160 to 190 in the home network 1000 through an Ethernet 150.

The input/output unit 120 receives an instruction from a user and displays necessary information to the user. For example, it applies to one of or a combination of user interfaces such as a mouse and a liquid crystal panel. Note that the input unit is an example of the instruction receiving unit.

The association generation unit 130 generates an association template which specifies details of service to be operated in association.

The association execution unit 140, in order to execute the associated operation, transmits the association template generated by the association generation unit 130 to the communication control unit 110 and stores information relating to the associated operation. Note that the association execution unit is an example of the association execution unit.

FIG. 2 is a block diagram showing a functional configuration of the association generation unit 130 shown in FIG. 1. As shown in FIG. 2, the association generation unit 130 has an association template management unit 131, an association template selection unit 132, an association implementation unit 133, a template adaptable service extraction unit 134, a service selection unit 135, a service adaptation unit 136, and a service adapter group 139.

The association template management unit 131 manages an association template in which details of the service association are described. Here, the “association template” is a file by which actual service can be defined later and in which an outline of details of an associated operation between services is previously described. Further, the association template management unit 131 holds a service declaration which is defined based on an instruction from a user. This “service declaration” is a declaration indicating details of a service defined in the association template. Note that the association template management unit is an example of the descriptor storage unit.

The association template selection unit 132 selects an association template in the association template management unit 131 based on the instruction received from the user via the input/output unit 120. Note that the association template selection unit is an example of the template specification unit.

The association implementation unit 133 defines actual service in the association template selected by the association template selection unit 132 and implements details of the service.

The template adaptable service extraction unit 134 extracts a service which is adaptable to the association template in the association implementation unit 133 via the communication control unit 110, that is, searches the service. Herein, the template adaptable service extraction unit 134 refers the service adaptor group 139 in accordance with the necessity. Note that the template adaptable service extraction unit is an example of the operation information search unit.

The service adaptor group 139 is a group of service adaptors (it also called as “conversion description”) and has a function of managing those service adaptors. The service selection unit 135 selects the service extracted by the template adaptation service extraction unit 134 based on the instruction from the user received via the input/output unit 120.

The service adaptation unit 136 adapts the service selected by the service selection unit 135 to the association template in the association implementation unit 133. Herein, the service adaptation unit 136 uses a service adaptor in the service adaptor group 109 in accordance with the necessity. Note that the service adaptation unit is an example of the operation description conversion unit.

According to the above configuration, based on details defined in the association template, it becomes possible to increase choices of services adaptable to the association template by extracting the adaptable service from the template adaptable service extraction unit 134. Therefore, a service association system in which the range of associated operation is not limited by the association path automatic generation capability of the system and the associated operations can be customized is realized.

FIG. 3 is a diagram showing a specific example of the appliance 160 shown in FIG. 1. As shown in FIG. 3, the appliance 160 is an umbrella with a function (more specifically, an umbrella with a lamp). When it receives weather forecast information about that it is going to rain from the weather information supply server, a LED installed in a handle lights up as the associated operation. Note that, the control unit 161 shown in FIG. 3 has a function of communicating with the communication control unit 110 through wireless LAN and the like and a function of controlling to light up the LED according to an instruction by the communication control unit 110.

FIG. 5 are diagrams showing examples of the service declaration held in the association template management unit 131.

Three service declarations are shown in a service declaration SV01 in FIG. 5A. As shown in FIG. 5A, it is indicated that the service defined in the declaration in the first line SV01L01 has a title “weatherServer1” and should input data of “Area type”, and that it is a service which outputs data of “Weather type” and provides weather forecast information. Similarly, it is indicated that the service defined in the declaration in the second line SV01L02 has a title “weatherServer2” and should input data of the “Area type”, and that it is a service which outputs data of the “Weather type” and provides weather forecast. Further, it is indicated that the service defined in the declaration in the third line SV01L03 has a title “newsServer 1” and does not need to input data, and that it is a service which outputs data in “News type” and provides news.

Also, it is indicated that the service defined in the declaration in the first line SV02L01 in FIG. 5B has a title “weatherDevice1” and should input data in “Weather type”; that it is a service without outputting data; and that it is operated by a home appliance having a display specific to weather forecast information (hereafter referred to as “weather display apparatus”). Furthermore, it is indicated that the service defined in the declaration in the second line SV02L02 indicates has a title “boolDevice1” and should input data of “bool type”; that it is a service without outing data; and that it is a service that operates a lamp which changes colors according to a data value (hereafter referred to as “lamp”).

FIG. 6 is a diagram showing an example of data to be used in an association template. The data ML01 shown in FIG. 6A is an example of data of the “Weather type”. The description in the second line ML01L02 “sunny” indicates that the weather is sunny. Here, the data of the “Weather type” can take values other than “sunny” such as “cloudy” indicating cloudy weather and “rainy” indicating rainy weather. The data ML02 shown in FIG. 6B is an example of data of the “Bool type”. The second line of the description ML02L02 “true” indicates that the value is “true”. Here, the data of the “Bool type” can take a value indicating “false” other than “true”.

Next, it is explained about an operation of a service association system 2000 configured as described above.

FIG. 4 is a flowchart showing a flow of operations of extracting a service appropriate to the association template.

First, the template adaptable service extraction unit 134, as a process before the extraction, specifies a location in the association template where the service is described, and initializes a service extraction list (S201).

The process before the extraction is explained with reference to an example of an association template shown in FIG. 7. The association template T07 in FIG. 7 is a template for describing associated services of, for example, repeating in every determined time (e.g. every 5 minutes) to receive weather information from the weather information supply server 10 and transmit the received weather information to a weather display apparatus.

The description in the first line T01L01 in FIG. 7 indicates that the association template has a title “WeatherTeller1.” and that area data of “Area type” to be transmitted to the weather information supply server 10 which receives the weather information can be set. The description in the second line T01L02 is a declaration for using data of the “Weather type”. The description in the third line T01L03 indicates to repeat the processes until the following description in the seventh line T01L07. The description in the fourth line T01L04 indicates to obtain weather information of the “Weather type” from the weather information supply server 10 called “WeatherServer”. The description in the fifth line T01L05 indicates to transmit the obtained weather information to the weather display apparatus called “WeatherDevice”. The description in the sixth line T01L06 indicates to wait for 5 minutes. The description in the seventh line T01L07 indicates a breakpoint of the repeated details. Further, the description in the eighth line T01L08 indicates an end of definition of the association template.

Note that, “specification of a part in the association template where the service is described” in the process before the extraction (S201) indicates to specify that a service called “WeatherServer” is described in the description in the fourth line T01L04 of the association template in FIG. 7 and that a service called “WeatherDevice” is described in the description in the fifth line T01L05.

Next, the template adaptable service extraction unit 134 searches a service appropriate to the service description specified in the process before the extraction (S201) via the communication control unit 110 (S202). When the appropriate service is found, it is added to the initialized service extraction list (S203). On the other hand, when the appropriate service is not found, it searches a service adaptor appropriate to the specified service description from the service adaptor group 139 (S204). When the appropriate service adaptor is found, it moves on to the process S205 and when it is not found, it moves on to the process S207.

Here, with reference to FIG. 8, it is explained about a service adaptor. This “service adaptor” is, for example, a “conversion description” in order to deal the lamp as a weather display apparatus. The description in the first line A01L01 in FIG. 8 indicates the “BoolDevice” such as lamp as a start of the conversion description for indicating as the “WeatherDevice” such as weather display apparatus and indicates to describe the title of the service adaptor as “rainyBool”. The description in the second line A01L02 indicates that the weather information of “Weather type” should be inputted as an interface of the “WeatherDevice”. The description in the third line A01L3 indicates that the following processes are ramified according to the value of the weather information. From the description in the fourth line A01L04 to the description in the sixth line A01L06, it is indicated that, when the weather information says rainy, data of the “Bool type” which is “true” is transmitted to the “BoolDevice”. From the description in the seventh line A01L07 to the description in the tenth line A01L10, it is indicated that, when the weather forecast says sunny or cloudy, data of the “Bool type” which is “false” is transmitted to the “BoolDevice”. In the process of searching the service adaptor (S204), the “rainyBool” in FIG. 8 can be found as a service adaptor appropriate to the description in the fifth line T01L05 in FIG. 7.

As a service appropriate to the description in the fourth line T01L4 of “WeatherServer” of the association template in FIG. 7, the description in the first line SV01L01 in FIG. 5 “weatherServer1” and the description in the second line SV01L02 “weatherServer2” can be found. Also, as a service appropriate to the description in the fifth line T01L5 in FIG. 7 “WeatherDevice”, the the description in the first line SV02L01 in FIG. 5B “weatherDevice1” can be found. In these examples, in order to judge whether the service description adapts to the service, a method of adapting the input/output data is used.

Next, a service appropriate to the specified service description is searched through the service adaptor found in the process S204 (S205). When the appropriate service is found, it moves on to the process S206 and when the appropriate service is not found, it moves on to the process S207.

The “boolDevice1” in FIG. 5B can be found as a service appropriate to the “WeatherDevice” in FIG. 7 through the “rainyBool” in FIG. 8.

Further, the service found in the process S205 is added to the initialized service extraction list (S206). In the case of the association template shown in FIG. 7, the “boolDevice1” in FIG. 5 is added.

In addition, the service extraction list including the service added in the processes S203 and S206 is edited and the result indicates the service extraction result (S207). In the case of the association template in FIG. 7, as a service appropriate to the “WeatherServer”, the “weatherServer1” and “weatherServer2” in FIG. 5 are extracted, and as a service appropriate to the “WeatherDevice”, the “weatherDevice1” and “boolDevice1” in FIG. 5 are extracted.

Through the above processes, the template adaptable service extraction unit 134 extracts a service. In the example of the association template in FIG. 7, an example of service association implemented in the service implementation unit 133 when the “weatherServer1” and the “weatherDevice1” are selected in the service selection unit 135 is shown in FIG. 9. The abstract service descriptions such as “WeatherSever” and “WeatherDevice” in the association template in FIG. 7 are implemented by the actual service of the “weatherServer1” and “weatherDevice1”.

Also, FIG. 10 shows an example of the service association implemented in the association implementation unit 133 when the “weatherServer1” and “boolDevice1” are selected in the service selection unit 135. FIG. 10 indicates a state where the description is implemented so as to operate by associating the operation of the weather information supply server 10 with the appliance 160 (umbrella with function) using the service adaptor in FIG. 8.

As described above, in the present embodiment, it becomes possible not only to adapt only an appropriate service simply to the association template, but also to adapt different types of services automatically to the association template. Consequently, it can achieve both of controlling the association template and of increasing the range of choices of the associated operations.

Note that in the present embodiment, it is explained that the association template is a description of abstract associated operations between services. However, if the services are changeable, specific associated operations between services may be described in the association template.

Here, a management method used in the association template management unit 131 may be a method of managing only the registered association template or a method of searching on the network. Similarly, when the template adaptable service extraction unit 134 refers the service, it may refer in a range of the pre-registered service or it may refer by searching a service on the network.

Similarly, when the template adaptable service extraction unit 134 refers a service adaptor, it may refer in a range of the pre-registered service adaptor or it may search and refer the service adaptor on the network.

Note that the association template may be described in advance statically in an association generation program instead of being obtained dynamically from the association template management unit 131. Also, by combining the association templates, some of the association templates may be described in a program and others may be obtained dynamically from the outside.

Note that, the service adaptor may be searched automatically by the system, selected by a user or automatically generated by the system. Also, when selecting the service adaptor among a plurality of candidates, the service adaptor may be determined with reference to personal information, statistical information, service adaptor evaluation value, a degree of association of the service adaptor with the service, or a degree of association of the service adaptor with the association template. The number of choices may be reduced and the display order of the choices may be determined as well.

The present system may be a system which adapts an appropriate service to the association template without using the service adaptor. That is, it may be a system without the service adaptor group 139 shown in FIG. 2. Similarly, in the system, the processes from S204 to S206 in FIG. 4 are deleted so that the process S202 or S203 may directly moves on to the process S207.

Here, since there is no service adaptor, the choices of services which are adaptable to the association template can be narrowed. However, it is possible to implement the association template and operate the service in association unless there is a service appropriate to the associated operation. In that case, the number of association templates is increased so that more various associated operations can be implemented. While controlling the increase of the number of association templates, the service adaptor can implement the various associated operations.

The service adaptor may be described in advance statically in the association generation program instead of being obtained dynamically from the service adaptor group. In addition, as a combination of the service adaptors, some service adaptors may be described in the program and some may be obtained dynamically from the outside.

Here, an instruction according to an association template and a service via the input/output unit 120 may be performed by a system in place of a user. Herein, the system may refer to the personal information, statistical information, association template evaluation value, service evaluation value and the like.

Note that each unit shown in FIG. 1 is not necessarily set on one computer. For example, the association template management unit, the association implementation unit, and the association execution unit may be arranged on different computers on the network. The association execution unit may be included in the other appliances. That is, it may be included in a server or an appliance for the user.

Here, each unit shown in FIG. 3 may exist one or more. For example, the association execution unit 140 may exist as many as users.

SECOND EMBODIMENT

FIG. 11 is a diagram showing a configuration of a service association system 2100 in the second embodiment according to the present invention. As shown in FIG. 1, in the service association system 2100, an appliance management server 60 of an appliance manufacturer A, an appliance management server 70 of an appliance manufacturer B and a service support server 80 of an association service support company are respectively connected to a home network 1100 through a network 50.

The home network 1100 includes an association control apparatus 200, an appliance 260, an appliance 270, an appliance 180, and an appliance 190. Further, the association control apparatus 200 has a communication control unit 110, an input/output unit 120, an appliance ID obtainment unit 210, an appliance service type judgement unit 220, an association generation unit 130 and an association execution unit 140. Hereafter, same mark is assigned to the constituent in the present embodiment which has same function as the constituent in the first embodiment and the explanation about the same constituent is therefore omitted.

The appliance ID obtainment unit 210 obtains an appliance ID from the appliance 260 or the appliance 270. The appliance service type judgement unit 220 judges a service type of the appliance 260 or the appliance 270 using the appliance ID and service ID obtained by the appliance ID obtainment unit 210.

The appliance 260 or the appliance 270 holds respectively an appliance ID 261 or an appliance ID 271 which is associated with each service type.

FIG. 12 is a diagram showing a specific example of the appliance 260 in FIG. 11. As shown in FIG. 12, the appliance 260 is an umbrella with a function (more specifically, an umbrella with a lamp or a melody performance function). When the appliance 260 receives weather forecast information indicating that it is going to be “rainy” from the weather information supply server, a LED installed in a handle lights up or performs melody as the associated operation. Note that, the control unit 261 in FIG. 12 has a function of communicating with the communication control unit 110 by a wireless LAN and the like and of controlling the LED to light up or to play melody according to an instruction of the communication control unit 110.

According to the configuration in the present embodiment, an associated operation relating to an appliance is generated by registering a service type of the appliance. As the result, it becomes possible to operate the appliance in association with other service groups.

Here, the service type includes a data type indicating input/output data relating to the appliance 260 or the appliance 270, a connection type indicating a connection format of these appliances and a constraint type indicating a constraint according to an input/output of the data.

As examples of the data type, there are a weather type indicating data relating to weather shown in FIG. 6 of the first embodiment and a binary type indicating binary data. It also applies to a data type such as news type, stock type, and traffic information type indicating data on the Internet, a data type such as an air conditioner type and a washer type indicating a condition or conditional change of an appliance, a data type such as speaker type, bell type and robot control type causing a conditional change of an appliance, a data type such as camera type and GPS type indicating information from an information obtainment appliance, and a data type such as mail type and a schedule type indicating information relating to an individual and a group. Further, it includes data type which combines these data types.

As examples of the connection type, there are a connection type such as Hyper Text Transfer Protocol (HTTP) type, Simple Mail Transfer Protocol (SMTP) type, an Internet Relay Chat Protocol (IRC) type indicating a communication protocol; a connection type such as push type and pull type indicating a direction of information flow; a connection type such as request type, and broadcast type indicating a type of trigger which flows information; a connection type such as full-time connection type and on-again connection type indicating connection frequency; and a connection type such as secret communication type and open communication type indicating a level of information security in a connection path. Further, it includes a connection type which combines these connection types.

As examples of the constraint type, there are a constraint type which limits a value of the data type or a range of the value; a constraint type such as service time type which defines service time, service day type which defines days of week when the service is provided, service holiday type which defines days when the service is not provided indicating time and the like when the service is provided; a constraint type such as membership type and personal information type indicating an individual who can receive the service; a constraint type such as associated appliance type and associated service type which constrains a method of using data by indicating an appliance and a service that are permitted for an association target; a constraint type such as total amount type and payment type indicating payment information for charged services; and a constraint type such as maximum number of associated appliances type and maximum workloads type indicating a supply capability of a service supplier. Further, it includes a constraint type which combines theses constrain types.

In the above configuration, the associated operation relating to the appliance is generated by registering the service type such as data type, connection type and constraint type. As the result, the appliance can be operated in association with a service group of other data types, connection type, and constraint type.

Here, the service adaptor explained in the first embodiment is an example of a service adaptor which adapts the weather type of “Weather type” to the binary type of “Bool type”. Using similar method, the service adaptor can adapt different data types to one another, different connection types to one another, and the different constraint types to one another. As an example of adapting different connection types, when the information obtainment request is requested in the HTTP protocol, in the case where there are an information supply server A of the connection type which can obtain the appropriate information and an information supply server B of the connection type which transmits information as a chat voice in the IRC protocol, a service adaptor can associate the information supply server A with the information supply server B as its connection type, the service adaptor executing an operation of repeating to transmit the information obtainment request to the information supply server A in every five minutes, transmits the obtained information as the chat voice, and to transmit a request to the information supply server A another five minutes later.

As an example of adapting different constrain types, in the case where there are an information supply server A holding a constraint on supplying information only in the morning and an information supply server B holding a constraint on supplying information only in the afternoon, a service adaptor which stores the data on the network can associate the information supply server A with the information supply server B as its constraint type.

Also, the service adaptor can adapt different types such as service type, data type, connection type and constraint type so that it can also adapt different types in an inheritance relationship. For example, in the case where there are, as a data type in the inheritance relationship, a “display data type” composed of character data and a “four characters display data type” composed of character data having four characters, the four character display data type inherits the character display data type since the four characters display type is one type of the display data type. Here, the service adaptor can be used for according the four characters display data type with the display data type. On the contrary, the service adaptor can also be used for adapting the display data type to the four character display data type.

Note that, as a method for the appliance to hold an appliance. ID, any one of the following methods may be used: a method of storing the appliance ID in the storing unit of the appliance; a method of printing the appliance ID on the appliance; a method of attaching the printed matter of the appliance ID to the appliance; and a method of having the appliance to hold an IC chip and a tag which hold the appliance ID. Also, as a method of transmitting the appliance ID to an appliance ID obtainment unit, any one of the following methods may be used: a method of transmitting the appliance ID from the appliance to the appliance ID obtainment unit through a communication path; a method of notifying the appliance ID obtainment unit of the appliance ID by a user; and a method of transmitting the appliance ID to the appliance ID obtainment unit after obtaining the appliance ID from the appliance using an appliance such as scanner and a camera.

THIRD EMBODIMENT

FIG. 13 is a display example of an association specification screen of an input/output unit (not shown in the diagram) of a service association system in the third embodiment according to the present invention.

In FIG. 13, an association specification screen G101 is a screen on which a list of services (hereafter referred to as “service list”) on the network 50 is displayed, indicating that there are services providing data of “weather forecast”, “stock price”, and “baseball score” on the screen. Also, as a list of appliances (hereafter referred to as “appliance list”), it displays a “television”, a “ticker” having a display apparatus, an “umbrella with function” and a “bell”. A black circle next to the weather forecast on the service list and a black circle next to the umbrella with function on the appliance list indicate that a user selects the weather forecast and the umbrella with function in response to the display.

Further, the association specification screen G102 shows, in the association specification screen G101 after a user selected the weather forecast and the umbrella with function, an example of a screen on which the display of services of stock price and baseball score are deleted from the service list, services of sound conversion and music conversion are displayed, and the displays of appliances other than a speaker are deleted from the appliance list. Here, by selecting, by a user from the service list, a service of sound conversions of a sound conversion (standard) or a sound conversion (comedy version), services and appliances necessary for outputting the weather forecast to a speaker are specified.

Next, it is explained about an operation of the present system configured as described above. FIG. 14 is a flowchart showing a flow of operations in the input/output unit.

First, the input/output unit starts specifying a service on the network 50 and an appliance which provides the service (S301). It then displays a list of the service and the appliance (S302).

Furthermore, the input/output unit receives an instruction to the display in the process S302 from a user (S303). In the example of FIG. 13, it receives an instruction to specify a weather forecast and an umbrella with function.

Next, it obtains a condition necessary for using the service and the appliance specified in the process S303 (S304). In the example of FIG. 13, the weather forecast is displayed in characters and a lamp installed in the umbrella with function lights up.

After that, it searches for the condition obtained in the process S304 (S305). Further, when the condition is found in the process S305, it searches for a service or an appliance which satisfy the condition (S306). When the service and the like which satisfy the condition are found, it moves on to the process S302. In the example of FIG. 13, it searches for a service and an appliance by which the umbrella with function can convert the character data supplied from the weather forecast. As the result, services of a light-up conversion and a music performance conversion are found.

Furthermore, it completes the specification when the condition being searched in the process S304 and the service and appliance being searched in the process S305 are not found (S307).

Through the above operations, the present invention can specify the associated operation by repeating to select a service and an appliance which provides the service when the user specifies the associated operation. As the result, it can correctly specify the service and appliance necessary for the associated operation without instructing at once.

Note that, a service which can be specified, a service which satisfies a condition of the appliance, and the appliance may be searched in advance. As the result, it can avoid selecting a service and appliance that cannot satisfy the condition in the end.

FOURTH EMBODIMENT

FIG. 15 is a diagram showing an example of an association specification screen in the input/output unit (not shown in the diagram) of a service association system in the fourth embodiment according to the present invention.

A black mark displayed next to the interlocking doll indicates that the user has instructed to operate the interlocking doll in association. Displays of “tomorrow from 18:30 to 21:00” displayed left to the East versus the West and of “next Sunday” displayed left to the package delivery status indicate that those services have not yet started and that those services are started at the indicated time. The user selects services which have not yet been started so that the user can instruct to operate the service in association with the interlocking doll in accordance with the start of the service.

FIG. 16 is a block diagram showing a functional configuration of an association control apparatus of the service association system in the fourth embodiment according to the present invention.

In FIG. 16, a service schedule obtainment unit 1302 obtains information indicating a service schedule from a service provider on the network 50 through a communication control unit 110. Note that, the service schedule obtainment unit is an example of the schedule information obtainment unit.

In the example of FIG. 15, it obtains information indicating a service schedule of “tomorrow from 18:30 to 21:00” from a service which provides a baseball score of the game of the East versus the West (hereafter referred to as “baseball score service”). Similarly, it also obtains information indicating a service schedule from the package delivery status service.

The service schedule management unit 1303 manages information indicating the service schedule obtained at the service schedule obtainment unit 1302.

A service schedule display/selection unit 1305 transmits information indicating a service schedule of the service schedule management unit 1303 to an input/output unit 1304 and receives an instruction from the user. In the example of FIG. 15, it displays the association specification screen G201 and receives selections of the interlocking doll as an appliance and a baseball score service as a service.

The association reservation management unit 1306 manages information relating to a service reservation selected by the service schedule display/selection unit 1305. In the example of FIG. 15, it manages information indicating time of 18:30 next day of the specified day as a start time of the associated operation.

The association generation unit 130 generates description for performing an associated operation relating to a service appropriate to the service reservation selected by the service schedule display/selection unit 1305. In the example of FIG. 15, it generates description for performing an associated operation in order to reflect data relating to the game obtained from the baseball score service with an operation of the association doll.

The association execution unit 140 operates, in association, service and the like in the service provider on the network 50 by the association reservation received from the association reservation management unit 1306 and the description for performing the associated operation received from the association generation unit 130. In the example of FIG. 15, the association execution unit 140, at 18:30 on the next day of the instructed day, obtains data relating to the game from the baseball score service, processes the data by the service adaptor if necessary, notifies the interlocking doll, and operates the interlocking doll.

In the above configuration, the associated peration relating to the service can be instructed before the service starts. As the result, the associated operation is performed soon after the service is started and the associated operation is terminated when the service is finished.

Here, the association execution unit may have started the associated operation before the start time of the service schedule unless the service and the information input/output are not before the start time. Similarly, the associated operation may be after the end time of the service schedule unless information input/output with the service is not performed later than the end time.

Note that, in the case where displaying the service schedule and where the associated operation is started/ended according to the service schedule, the displayed service schedule may be changed and the start time and end time of the associated operation may be changed with reference to user's schedule from a scheduler of the user, services other than the service, a schedule of an appliance and the like without using the determined service schedule time.

SEVENTH EMBODIMENT

Whereas a block diagram showing a functional configuration of a service association system in the seventh embodiment according to the present invention and an operation relating to a service extraction are basically same as those in the first embodiment, hereafter only the differences are explained.

FIG. 19 is a diagram showing a service example in a service association system (not shown in the diagram) in the seventh embodiment of the present invention. A description SV03 shown in FIG. 19 is an example of a declaration of two services. A service indicated in the description in the first line SV03L01 is a service by a head mount display (hereafter referred to as “HMD”) which is a head mount type information display unit, indicating that its title is “HeadMountDisplay”, data of “Contents type” is inputted and displayed, and that data of “Presence type” should be inputted. Here, the “Contents type” is a data type indicating information and content to be displayed to the HMD. The “Presence type” is a data type indicating to display HMD in how much degree of presence. The data of “Presence type” is described in a value indicating a degree such as 30% and 100%. The higher the value, the more screen size and volume are increased and the HMD displays information in a higher presence. On the other hand, the lower the value, the more screen size and volume are reduced and the HMD displays information in a lower presence. If the presence is higher, the user can view the information in immerse. If the presence is lower, the user can view information while doing something other than viewing the information. Also, a service shown in the description in the second line SV03L02 is a service by a sensor device which detects a motion of the user and outputs “Motion type” data. The “Motion type” is a data type indicating a type of the motion of the user. It indicates “moving” when the user is moving and “still” when the user is in still.

FIG. 20 is a diagram showing an example of a service adaptor in the present embodiment. The service adaptor in FIG. 20 is a conversion description which makes it possible to use the HMD as the weather display apparatus. The description in the first line A02L01 indicates a start of the description converting the HMD into a “Weather Device” such as the weather display apparatus and that the title of the service adaptor as “WeatherHMD”. The description in the second line A03L02 indicates weather data of the “Weather type” as an interface of the “WeatherDevice”. The description in the third line A03L03 indicates to obtain a type of a motion of a user from the sensor device. The description in the fourth line A03L04 indicates to divide later processes according to the obtained type of a motion of a user. It is indicated that, from the description in the fifth line A03L05 to the description in the seventh line A03L07, in a state where a user is moving such as walking, the weather is displayed to the HMD in a low presence. It is indicated that, from the description in the eighth line A03L08 to the description in the tenth line A03L10, in a state where a user is in still such as sitting, the weather is displayed to the HMD in a high presence.

Using the above service examples and the service examples explained in the first embodiment, an operation of extracting a service adapted to an association template is explained with reference to the flowchart shown in FIG. 4.

First, a process before an extraction is performed (S201). Using the association template of FIG. 7, the similar processes as in the first embodiments are performed.

Next, a service in accordance with the service description specified in the process S201 is searched on the network 50 (S202). When the appropriate service is found, the process moves on to the process S203. When the appropriate service is not found, the process moves on to the process S207. In the case of the association template in FIG. 7, as a service appropriate to the description in the fourth line T01L4 “WeatherServer”, the description in the first line SV01L01 “weatherServer1” in FIG. 5 and the description in the second line SV01L02 “weatherServer2” can be found. Also, as a service appropriate to the description in the fourth line T01L05 “Weather Device”, when the user is at home where the “weatherDevice1” is set, the description in the first line SV02L01 “weatherDevice1” in FIG. 5 can be found. When the user is not at home, the service appropriate to the “WeatherDevice” cannot be found.

Further, the service found in the process S202 is added to a service extraction list initialized in the process S201 (S203).

After that, a service adaptor appropriate to the service description specified in the process S201 is searched in the service adaptor group 109 (S204). When the appropriate service is found, the process moves on to the process S205. When the appropriate service is not found, the process moves on to the process S207. In the step of searching the service adaptor, in the case of the association template in FIG. 7, as a service adaptor appropriate to the description in the fifth line TL01L05 “WeatherDevice”, the “rainyBool” in FIG. 8 and the “WeatherHMD” in FIG. 20 can be found.

Through the service adaptor found in the process S204, a service appropriate to the service description specified in the process S201 is searched from the service group 110 (S205). When the appropriate service is found, the process moves on to the process S206. When the appropriate service is not found, the process moves on to the process S207. Through the “rainyBool” in FIG. 6, as a service appropriate to the “WeatherDevice” in FIG. 5, when the user is at home, the “boolDevice1” in FIG. 3 is found. When the user mounts the HMD and is in outside, the HeadMountDisplay in FIG. 6 is found. Thus, according to place, time, device exists in periphery of the user, a service and device suitable to the user at that time are selected. An operation in the case where the “boolDevice1” is found is same as the operation explained in the first embodiment.

Next, hereafter explains about an operation in the case where the “HeadMountDisplay” is found.

The service found in the process S205 is added to the service extraction list initialized in the process S201 (S206). In the case of the association template in FIG. 7, the “HeadMountDisplay” in FIG. 19 is added.

Lastly, the service extraction list including services added at the process S203 and the process S206 is edited and the result becomes the service extraction result (S207).

In the case of the association template in FIG. 7, as a service appropriate to the “WeatherServer”, the “weatherServer1” and the “weatherServer2” in FIG. 5 are extracted, and, as a service appropriate to the “WeatherDevice”, the “HeadMountDisplay” in FIG. 19 is extracted.

Through the above operations, a service is extracted by the template adaptable service extraction unit 1034. As an example of the association template in FIG. 7, in the service selection unit 135, when the “weatherServer1” and the “HeadMountDisplay” are selected, an example of a service association implemented by the association implementation unit 133 is shown in FIG. 21. Abstract service descriptions such as the “WeatherServer” and the “WeatherDevice” in the association template in FIG. 7 are implemented by an actual service of the “weatherServer1” and the “HeadMountDisplay”. By using the service adaptor in FIG. 20, the description is implemented to a description for operating the weather forecast server in association with the HMD. By executing the association description in FIG. 21, when the user is in outside mounting a permeable HMD and walking, the weather forecast is displayed in a lower presence with smaller screen size and volume. When the user is in outside and sitting, the weather forecast is displayed in a higher presence with larger screen size and volume. Thus, such service association is implemented.

Note that, in order to select a service and decide data to be inputted to the service, as shown in FIG. 20, a sensor which sensors a motion of a user and other information relating to the user may be used. The physical state of the user may be used by obtaining from a sensor such as GPS, acceleration sensor, thermometer, sphygmomanometer, camera, ammeter, and voltmeter. The mental state of the user may be used by obtaining or predicting from a camera, sphygmomanometer, blood flow meter, sight, electroencephalograph, expression, diaphorimeter, voice, gesture, stress-meter and the like. Also, the behavioral state of the user may be used by obtaining or predicting from a scheduler, objective list, traffic condition, weather forecast, peripheral goods, merchandize inventory, map, data collection of behavioral characteristics, behavioral records, and behavior of others.

Although only some exemplary embodiments of this invention have been described in detail above, those skilled in the art will readily appreciate that many modifications are possible in the exemplary embodiments without materially departing from the novel teachings and advantages of this invention. Accordingly, all such modifications are intended to be included within the scope of this invention.
